ABB drives reduce chilled-water energy bill

Eight ABB standard drives are saving Ginsters bakery a potential 17 per cent annually on its chilled-water energy bill, following installation on chiller pumps at its Callington bakery in Cornwall.

APDS measured the power consumption of the Ginsters’ chilled-water pumps over 24 hours and analysis showed that using a variable speed drive to achieve a speed reduction of 6 per cent would reduce energy consumption, and therefore operational costs, by 17 per cent.

A trial installation of an ABB drive showed improved stability of the system and reduced power consumption.
